How does the tee-lady compare?

We asked an expert to compare the tee-lady to the small blue. Here is what he said.

It’s a very exciting time. I understand that the tee-lady has been in development for two years. The tee-lady follows exactly the same design principles as the small blue. I believe that the tee-lady is as effective as the small blue, which is as effective now as it was when it was first launched.
